Where is the singularity in the following 3-sequential Euler Angle Rotation matrix about the ZY'Z'' axis where Y' is the new Y axis after the first Z rotation and Z'' is the new Z axis after the Y' rotation.
The matrix has been generated seen below, but I'm having trouble finding the singularity:

In the 3D Cartesian system the rotation matrix is around the
z-axis is (a 2D rotation):
Where
is the angle to rotate. Then rotation from A to A' is can be
represented via matrix multiplications: [A'] = [R][A]
Such a rotation is useful to return a system solved in
simplified co-ordinates to it's original co-ordinate system,
returning to original meaning to the answer. A full 3D rotation is
simply a series of 2D rotations (with the appropriate matrices)

If U(,) refers to a rotation through an angle ß about the y-axis, show that the matrix elements (j, m|U(B, Ý)|j, m'), -ism, m' Sj, are polynomials of degree 2j with respect to the variables sin (6/2) and cos (B/2). Here [j, m) refers to an eigenstate of the square and z-component of the angular momentum: j2|j, m) = jlj +1) ħaj, m), İzlj, m) = mħ|j, m).
Problem: Given a rotation R of R3 about an arbitrary axis through a given angle find the matrix which represents R with respect to standard coordinates. Here are the details: The axis of rotation is the line L, spanned and oriented by the vector v (1,一1,-1) . Now rotate R3 about L through the angle t = 4 π according to the Right 3 Hand Rule Solution strategy: If we choose a right handed ordered ONB B- (a, b,r) for...
10. The group of rotation matrices representing rotations about the z axis by an angle a: -sin α 0 cos α R,(a)--| sin α cos α 0 can be viewed as a coordinate curve in SO(3). Compute the tangent vector to this curve at the identity. Similarly, find tangent vectors at the identity to the curves representing rotations about the a axis and about the y axis. Is the set of these three tangent vectors a basis for the tangent...
5. (3 pts) Any operator that transfors the same way as the position operator r under rotation is called a vector operator. By "transforming the same way" we mean that V DV where D is the same matrix as appears in Dr. In particular for a rotation about the z axis we should have cos p-sinp0 sincos 0 0 where φ is the angle of rotation. This transformation rule follows frorn the generator of rotations where n is the unit...
A general finite rotation by an angle Φ about the axis with unit normal n, (n_k n_k = 1), is described by ¯xi = A_ij x_j where the components of the matrix A_ij are given A_ij = cos Φ δ_ij + (1 − cos Φ) n_i n_j + sin Φ ε_ijk n_k. Evaluate A_ij A_iℓ explicitly to show that A_ij A_iℓ = δ_jℓ
(a) Let T: R2 + R2 be counter clockwise rotation by 7/3, i.e. T(x) is the vector obtained by rotating x counter clockwise by 7/3 around 0. Without computing any matrices, what would you expect det (T) to be? (Does T make areas larger or smaller?) Now check your answer by using the fact that the matrix for counter clockwise rotation by is cos(0) - sin(0)] A A= sin(0) cos(0) (b) Same question as (a), only this time let T...

3.1 Rotations and Angular-Momentum Commutation Relations 159 We are particularly interested in an infinitesimal form of Ry: (3.1.4) where terms of order & and higher are ignored. Likewise, we have R0= ° :- R(E) = 1 (3.1.5) and (3.1.5b) - E01 which may be read from (3.1.4) by cyclic permutations of x, y, zthat is, x y , y → 2,2 → x....

Consider the following problem. Maximize Z= cixi + c2x2 + C3X3 subject to x1 + 2x2 + x3 = b 2x1 + x2 + 3x3 = 2b and x 20, X220, X2 > 0. Note that values have not been assigned to the coefficients in the objective function (C1, C2, C3). and that the only specification for the right-hand side of the functional constraints is that the second...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
